From 3961532fd41f13e6d6958c44c0ccc567da144a79 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 30 Oct 2013 09:18:21 +0100 Subject: [PATCH] 6lowpan: remove unnecessary set of headers On receiving side we don't need to set any headers in skb because the 6LoWPAN layer do not access it. Currently these values will set twice after calling netif_rx. Signed-off-by: Alexander Aring Reviewed-by: Werner Almesberger Signed-off-by: David S.
